A year ago, the Islamic State militant group declared a caliphate spreading from Iraq and Syria. Since then, the group has consolidated control over its territory in Iraq and Syria while also establishing itself as the world’s premier Islamist terrorist group. It has won the allegiance of jihadi fighters around the world and led to the establishment of Islamic State affiliates in several countries across the Middle East and North Africa.

According to a recent analysis carried out by IHS Jane’s Terrorism and Insurgency Center, the Islamic State has carried out 3,097 attacks in the last year. The map below shows those attacks and uses black borders to delineate the provinces claimed by the Islamic State. Nigeria is excluded, as territory under the control of the militant group Boko Haram has not been formally proclaimed a province, or wilayat, of the Islamic State, according to IHS. Boko Haram has pledged allegiance to the Islamic State, meaning it will likely be included soon.
